This publication provides guidance and advice on technical matters related to the design, building, operating, maintenance and repair of the corrosion protection systems of ships’ ballast tanks. This book provides options and information for designers, shipyards and ship owners and is specific enough to be used as a reference document for shipbuilding, ship repair and ship maintenance purposes.

In this edition, the text has been editorially revised and retypeset and all figure drawings recreated.
